摘要

本文提出了压缩域视频缩小的新方法。它是基于运动补偿的JPEG2000 (MCJ2K)视频压缩方案。我们已经开发了用于转码预编码MCJ2K流的算法的性能界限。研究了算法的效率和重建质量之间的权衡。所提出的算法在权衡方法效率的基础上产生了令人鼓舞的结果。

New Approaches for Video Transcoding in the Compressed Domain

This paper proposes new approaches for downsizing video in compressed domain. It is based on Motion-Compensated JPEG2000 (MCJ2K) video compression scheme. We have developed performance bounds on algorithms for transcoding the pre-coded MCJ2K stream. The tradeoffs between efficiency and reconstruction quality of the algorithms have been examined. The proposed algorithms produce encouraging results with tradeoff on the efficiency of the methods.
